Peripheral vascular disease (PVD) is associated with impaired neurocognitive recovery in acute traumatic brain injury (TBI) patients. There is sparse amount of literature reporting the impact of PVD on outcomes in this population. This study aims to further investigate the common comorbidity of PVD and its effects on the outcomes of short-term in-hospital patients after acute TBI.
This retrospective cohort study utilized the Nationwide Inpatient Sample to identify patients(18+) from 2012-2014 with a primary diagnosis of acute TBI. ICD-9 codes were used to identify patients with PVD and to exclude patients with history of TBI, diabetes insipidus, or missing identifiers(age, gender, death). Data analyses assessed length of stay(LOS), total hospital charges, age of admission and mortality.

Participants (or Animals, Specimens, Cadavers) :
Patient encounters documented in Nationwide Inpatient Sample Database.
Main Outcome Measure(s) :
Mortality, total in-hospital charges, length of stay, age of admission.
Of the 26,628 with a primary diagnosis of acute TBI, 1,532 patients were pre-disposed with PVD. In comparison to patients without PVD, significant increases were observed in the PVD group:
· Increased LOS (4.38 days vs. 5.42 days,p
· Increased total charges ($57,985.02 vs. $62,283.16,p
· Increased mortality (1.1% vs. 2.9%,p
· Increased age at admission (50.76 vs. 69.36 years,p
Patients with concomitant PVD who are diagnosed with acute TBI suffer from increased LOS, total charges and mortality. The results of this study can aid clinicians in making clinical decisions within this population. Limitations include inability to determine severity of PVD or TBI. Peri-procedural optimization of symptomatic patients is one avenue to improve patient outcomes.
